Earthquake:shaking/trembling of rocks underneath Earth's surface Stress:the force that acts/pushes on a rock to change it Shearing:form of stress that pushes two large pieces of rock in opposite directions Tension:form of stress that pulls apart a rock so that the middle is thinner than that of the sides/edges Compression:form of stress that squeezes rock until it folds or breaks Deformation:change of volume or shape in Earth's crust Fault:a place where two rocks have slipped past each other Strike-slip Fault:a fault where two rocks have slipped past each other with very little to no up-down motion Normal Fault: a normal fault is at an angle, so that one side is on top, and the other is on the bottom Reverse Fault:similar structure to a normal fault except for that they move differently Fault-block mountain: A mountain that forms where a normal fault lifts a block of rock. Fold: A bend in rock that forms where part of the Earth's crust is compressed. Anticline: A fold in the rock that bends upward Syncline: A fold in the rock that bends downward Plateau: A large area of flat land elevated high above sea level.
